Abstract
The embodiment of the invention discloses a channel estimation method for a TD-SCDMA system. The channel estimation method comprises steps of: obtaining a coarse channel estimation of a channel 1 of an intra-frequency cell set by a single cell channel estimation algorithm; performing an interference cancellation on the coarse channel estimation to obtain a channel estimation; determining a channel environment according to the channel estimation; and determining a stop strategy for the interference cancellation according to the channel environment and controlling performing the interference cancellation according to the stop strategy. The embodiment of the invention also discloses a channel estimation apparatus for a TD-SCDMA system, a communication device and a computer program executing the channel estimation method.
